Describe your Drinking-Water System The Woodward Treatment Facility supplies a significant portion of Hamilton s population with drinking water including Stoney Creek, Dundas, Ancaster, Waterdown, Flamborough and Glanbrook. The population served is estimated at 537,000. In addition, the treatment system provides treated water to parts of the Haldimand County (Caledonia, York and Cayuga) and parts of Halton Region.

2 The intake is comprised of three intake pipes: 1.22m, 1.52m and 2.44m in diameter that extend into Lake Ontario 640m, 915m and 945m respectively. The 2.44m and 1.52m diameter intakes are currently in use. The water treatment process consists of pre-chlorination of raw water, screening, and water clarification by coagulation, sedimentation and filtration. Chlorine for disinfection can be added at three places: raw water intake, the pretreatment stage, and after the filters. Polyaluminum chloride is added to coagulate suspended solids that settle down in sedimentation tanks. The settled water is filtered using dual media filters of Sand/Granular Activated Carbon (GAC). GAC is used to reduce the presence of taste/odour causing compounds such as Geosmin/MIB in the raw water. Taste and odour episodes may occur in late summer, due to the abundance of algae. Ammonia is added before the treated water is sent to distribution to convert chlorine to mono-chloramine to help maintain stable chlorine residuals in the distribution system. Fluoride is added to the drinking water to promote dental health. Water is then pumped from a high lift pumping station through the distribution system comprised of 21 pumping stations; 12 reservoirs, 3 elevated storage tanks and one standpipe. Continuous monitoring equipment such as chlorine analyzers, turbidity meters, etc., ensures the maintenance of high quality water. List all water treatment chemicals used over this reporting period.

3 Woodward Water Treatment Facility - Condition Upgrades (Design) Woodward Water Treatment Facility - Corrosion Control Building (Construction) The above water treatment and water station upgrades and modifications are being undertaken at a cost of approximately $12.2 million. Distribution System Pipes: As part of the City s Linear Asset Management Program, the following water upgrades and rehabilitations were completed in 2017: Approximately 7.3 km of watermain was replaced as a stand-alone project and\or in coordination with roadwork at a cost of $6.5 million. Approximately 6.6 km of watermain was rehabilitated using structural and\or cement mortar lining at a cost of $8.7 million. Provide details on the notices submitted in accordance with subsection 18(1) of the Safe Drinking-Water Act or section 16-4 of Schedule 16 of O.Reg.170/03 and reported to Spills Action Centre. Notification Date Location of Adverse AWQI Resolution Fire Station Fleet Maintenance, 177 Bay St. N. Total Coliforms = 6 Resampled adverse location, one upstream and one downstream hydrant. All results passed. The adverse was not confirmed Ancaster Sampling Station A Total Coliforms = 3 Resampled adverse location, one upstream and one downstream hydrant. Result failed at upstream hydrant which resulted in another AWQI July 27 th. The adverse was confirmed Hydrant AN15H006, Jerseyville Rd. Total Coliforms = 2 Flushing was done to get the chlorine residual to 1.0 mg/l or higher. Two consecutive sets of samples were taken 24 to 48 hours apart at the original adverse location, the adverse hydrant, one upstream and one downstream hydrant. Results for the both sets of samples passed. Microbiological testing done under Schedule 10, 11, 12 and 17, 18 of Regulation 170/03, during this reporting period.
